On their bodies were tattoos with the inscription, “The great Kaka”, which raised the suspicion that they belong to a cult.

They were paraded in handcuffs and leg chains at the 2 Division headquarters.

The gang leader, Emmanuel, said they only wanted to rob the officer. He blamed Satan for the crime.

The arrest of the six suspects came two days after the police freed five suspects, who were detained at the State CID.

The initial five suspects, two soldiers and three civilians, were granted bail at the state CID, Iyaganku, Ibadan, where they were detained for a month and four days.

The police said there was no evidence linking them to the killing.

Narrating how the six suspects were apprehended, the Division’s Deputy Director, Col. Timothy Antigha, said the killers were picked up at various locations through the help of the police and the Department of State Security (DSS).

The Army spokesperson, who was flanked by the Commandant of the Military Police (MP), Col. Abdullahi Haruna Ibrahim, told reporters the suspects took away the victim’s phone.

He said: “The phone, a Samsung S4, was found in Emmanuel’s possession. He claimed he got the phone from Adeniyi.

“He also stated that on the night of December 11, he and other suspects went to the victim’s house in a grey Toyota Camry belonging to Obi.

“Kehinde confirmed that Obi’s car was used for the murder. He described the late senior officer vividly as well as the cloth he wore at the time of their attack.

“Adeniyi said he was notified of the plot to attack the late senior officer by Kehinde.

“Andrew stated that he was with Kehinde, Adeniyi, Obi and Onusa-Uze during the murder. Obi provided the logistics for the operation as his vehicle was used to move the gang to and from the victim’s home. Onusa-Uze was mentioned by others as being a member of the gang.”

Leader of the investigation team Col. Ibrahim said Emmanuel was expelled from the school in 2015 for stealing and bad behaviour. He added that he led the others to the late commandant’s home.

Col. Ibrahim advised parents to always ensure they monitor the kind of friends their children keep.

The six suspects, he said, on December 12, after entering Col. Okeyim’s house switched off the generator before carrying out their mission.

He said the suspects and available evidence would be handed over to the police for further action.
